China Qing Dynasty Wrong Edition Coins

I want to know more people's opinions on the value of this coin, and if the price is reasonable, I would like to sell this coin. It is a Guangxu ingot, reversed, and the angle difference between the front and back is about 160 degrees. It was made by the Ministry of Households (Central). I have checked it on the Internet. The central Guangxu ingot is rare. This kind of large angle Mistakes are even rarer, I haven't seen a few. My Twitter @red886996, I am now in China.
